This book is aimed at data analysts using Excel as their everyday tool, who need to go beyond Power Pivot and use add-ins and other advanced tools. Excel experts wanting to expand their knowledge to take advantage of the new connection possibilities between Excel and Azure will also benefit, as will project managers needing to test machine learning models without writing code.
It is generally taken for granted that, in order to do data science, from data cleansing to visualization and machine learning models, you need to be a Python or R programmer. This is not the case nowadays, and the general tendency seems to be heading toward code-free data science. The reader needs to learn that there are other options, avoiding code to take Excel to the next level and use it as a platform for professional data analysis and visualization.
